MarkeTrak Issues – Premature closing of IGL/Rescission Subtypes  2/3/15 and 2/11/15 a large number of MTs (IGL and customer rescission) prematurely auto-closed  The “clock” for auto-closure had changed from 15 days to 15 minutes  ERCOT was unable to root cause the revision  Since, 2/11/15, ERCOT has installed additional audit/logging functionality so should this occur again, ERCOT will have the ability to trace the origin  Remediation plans, should this issue recur, is the following.. ◦ Market notice as soon as possible ◦ ERCOT to provide a list of impacted MTs available to REPs via a link in MIS and noted on the official market notice

MarkeTrak SLO Results-  MTTF, ERCOT, and API Users (Oncor and CenterPoint) have been reviewing the current SLOs established for API response times  Current methodology calls for the measurement of “test cases”  ERCOT has presented data for the simple averages of actual response times experienced for the various query searches  ERCOT will confer with API Users to compare results of data for the January and February response times  Next steps: possible revised SLO or addition of new metric
